This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

In this activity, learners explore the concept of permeability to better understand why amphibians are extremely sensitive to pollution.

In a class demonstration, learners observe a simple water cycle model to better understand its role in pollutant transport.

In this demonstration, learners observe vinegar and baking soda reacting to form carbon dioxide (CO2) gas.

In this activity on page 27, learners perform an experiment to learn about how different types of marine debris degrade and how weather and sunlight affect the rate of degradation.

In this activity on page 24, learners perform experiments to examine whether or not trash can float, blow around, or wash away.

Learners investigate the properties of the liquids in two bottles. One contains layers of oil and water, and one contains oil, water, and soap.

Learners discover that their breath contains carbon dioxide, one of the pollutants found in car exhaust.

In this activity (on page 2 of the PDF), learners explore surface tension by adding pennies to cups which are "full" of plain water or soapy water.

In this environmental science activity (page 4 of the PDF), learners use vinegar and chalk to observe the effect of acid rain on various building materials and plant life.

In this environmental science and data analysis activity, learners work in groups to track a Dead Zone (decreased dissolved oxygen content of a body of water) using water quality data from the Nutrien

In this activity, learners play NOAA's Carbon Tracker game and discover ways to keep track of carbon dioxide and other greenhouse gases in the world.
